IMPROVEMENT IN FURNAC ES FOR STEAM-GENERATORS.

Specification forming part of Letters Patent No. 181,682, dated August 29, 1876; application filed July 1,1876.

To all whom it may concern:

Be it known that we, REUBEN J ENKINs and HENRY RUDGE, of Chicago, in the county of Cook and' State of Illinois, have invented a new and valuable Improvement in Steam-Generators; and we do hereby declare that the following is a full, clear, and exact description 'of the construction and operation of the same,

K ments in steam-generators, as will be hereinafter more fully set forth.

In the accompanying drawings, A designates a boiler or steam-generator of any ordinary construction, which is set into and sus tained by a casing, B. A A are pipes or fines traversing said boiler, and opening at one end into combustion-chamber O at the rear end under the boiler, inside of said casing, and at the other end opening into the escape-flue or the air outside. A is a pipe extending from the bottom of said boiler through said casing, and allows the water contained in the boiler to be drawn off at will. D D E E are cells or boxes arranged along one side of said chamber, and against one of the upright walls of casing-B. In said wall are doors E E, communicating with said cells. F F are gas-pipes, communicating with the generator or reservoir of carbonic oxide, and with cells E E. G G are air-pipes, communicating at one end with some air-heating device or hot-air reservoir, and at the other end with cells D D. The pipes F and G are arranged alternately with reference to the cells, only one pipe communicating with each cell. Thus gas-receiving cells alternate with air-receiving cells, and as their tops are left open, the contents mingle in combustion-chamber O. The air introduced through the pipes G G is sufficiently hot to ignite the carbonic-oxide gas, and thereby to generate steam in boiler A. This is facilitated by tubes A A through which the products of combustion pass in escaping from the apparatus. Pipes El and G G are arranged partly or Wholly at such a height thatthe burning gas and heated air of the combustion-chamber will circulate around them, and thereby heat their contents, thus facilitating the above-described operation, and lessening the initial amount of heat required for heating the air in pipes G. The air-pipes G are each provided with door, valve, or cutoff -H, for regulating'the supply of hot air.

What we claim as new, and desire to secure by Letters Patent, is-

The combination of pipes F and G, in combustion-chamber O, with cells D D E E and pipes or flues A A substantially as and for the purpose set forth.

In testimony that we claim the above we have hereunto subscribed our names in the presence of two witnesses.
